I tested negative for hiv in late 2013, October 2016 and December 2017. But my nose always feels stopped up, and last few days my tongue has small bumps on it and if I roll my tongue it appears cracked. Is this a sign of oral thrush, does a negative hiv test is 2016 and 2017 after possible exposure in summer and winter of 2012 considered conclusive. My tongue at times looked white, but after bushing it looks pink, and right now is pink. Would the while permanently stay of it was thrush from hiv? Or were my results conclusive?
